GogangraZBK is distinguished from GagataZBK by having the outer and inner mental barbels widely separated, with the origin of the inner barbels anterior to the origin of the outer barbels (vs. barbels close together with their origins nearly parallel) and by having the branchiostegal membranes free from the isthmus (vs. broadly fused to the isthmus). GogangraZBK is distinguished from NangraZBK by having maxillary barbels extending only to the pectoral-fin base (vs. extending to the pelvic-fin base), by having nasal barbels shorter than the eye diameter (vs. longer than the eye diameter, reaching at least to the eye), by having small serrations on the anterior margin of the pectoral spine (vs. no serrations), and by the absence of palatal teeth and a well-developed maxillary barbel membrane. GogangraZBK is distinguished from BagariusZBK by having only small conical teeth in the lower jaw (vs. teeth in lower jaw markedly heterodont), by having small serrations on the anterior margin of the pectoral spine (vs. no serrations), and by the lack of a welldeveloped maxillary barbel membrane. GogangraZBK is distinguished from SisorZBK by having small (vs. large) serrations on the anterior margin of its pectoral-fin spine, no bony plates on the dorsum, no spine in the adipose fin, the origin of the inner mental barbels anterior ( vs. posterior) to the origin of the outer mental barbels), branchiostegal membranes free from the isthmus (vs. broadly fused to isthmus), the uppermost caudal-fin ray not greatly elongated (vs. greatly elongated, more than half the length of the body), and no welldeveloped maxillary barbel membrane.
